For the purpose of clarity, in the drawings, B indicates the contactblock. The contact block may be of any configuration and size asillustrated in the various modifications shown in the drawings. Theblock B may be of any non-conductive material such as wood, plastic, orthe' like. In some instances the block could be made from metal, thoughnon-conductive material would have to insulate the circuit areas.

C is a cable, or rod, or the like as generally indicated in thedrawings. The cable or contact connector C may be made of anynon-conductive material. It is possible that the cable could beconstructed of a metal material though the cable would for most types ofprogramming necessarily be covered with an insulating material.

The blocks B are provided with passageways P in which the contactconnector, cable, or switching member C slides and is drawn orpushedthrough. In the block B are openings which run from the outersurface of the block through and open into the passageways P. Theopenings generally indicated as X serve as receptacles for members Ysuch as contact plugs, as generally indicated in FIG- URES 4 and 5,contact switches as generally indicated in FIGURES 24 and 25 or othertypes of switches such as micro-switches which would operate in a mannerhereinafter set out.

FIGURES 1 to 3 FIGURES 1, 2 and 3 illustrate how two member-s C may passthrough the block B transversely with respect to each other. Asillustrated in FIGURES 1, 2 and 3, circuit can be made from Y1 to Y2 bya conductive coated surface on the cable C and similarly from Y3 to Y4.If Y members 1, 2, 3 and 4 are of the pressure sensitive type, then eachcable C would be operating to make or break two switches each in contactwith its respective FIGURES 4 to 10 In FIGURES 4 and 5, the lead It isclamped or otherwise held in a sleeve 12. A resilient spring or the like14 biases a ball 16 downwardly into an opening 18 in the sleeve 12. Theball 16 serves as a contact connector or as the pressure sensitivecontact member of a micro-switch or the like.

FIGURE 6 shows a manner in which the members Y and Y6 are conductivelyconnected for circuitry between each other through the cables C havingconductive areas thereon and through the intermediate conductor 2%?generally shown as a coil 22 having ball contact members 24 at eitherend thereof for engagement with the cables C.

FIGURES 7 and 8 illustrate two different types of cables which aremounted in a fitting sleeve 30. The sleeve in its entirety fits into thepassageway P. The sleeve 39 contains a member 32 having an openingtherein 34 conforming to the desired cable C to be used. Various sleeves30 may be interchangeably used.

FIGURES 9 and show a circular block B having a contact connector C aportion of which operates two pressurized microswitches 40 operatinglights 42 while simultaneously making a circuit between lead 44 and lead46 to operate a light 48.

FIGURES I] to FIGURE 11 shows a contact connector C having a raisedportion 50 which would operate the micro-switches or any pressuresensitive switch and a portion 52 which is conductive to make a circuitbetween two contacts which would be in a position similar to contacts 44and 4-6 as in FIGURE 10. FIGURE 12 merely illustrates how a cable C mayhave recessed portions 54 and raised portions 55 for operating variouspressure type switches and the like.

FIGURES 13, 14 and 15 illustrate how members Y may be operated by an Xtype cable C as in FIGURE 14. Cable C in FIGURE 14 is provided withbeads 53 which serve as guide members for the cable as it passes throughthe block B. Nylon or Teflon are excellent bearing materials forproviding ease of travel through the block B. FIGURE 14 shows conductivemember 60 traveling from one surface around and about one leg of theX-shaped cable C to another surface on another leg of the X-shaped cableC.

FIGURE 15 illustrates how a portion of the block shown in FIGURE 13 canbe used while another portion is inoperative by merely having two beads61 connected by a flat webbing portion 62 on which may be printedvarious conductors 63, 64- and 65. The conductive surfaces would engagethe desired pair of contacts Y, or in the case of micro-switches, theraised portions on the webbing 62 would actuate the pressure sensitivesurfaces heretofore referred to.

FIGURES 16m 18 FIGURES 16, 17 and 18 illustrate a contact block B havinga pair of opposed bearing plates 7%) and '72 resiliently biasing aseries of cables C. The opposed bearing plates 70 and 72 are recessed insuch a manner as to support the particular configuration of the cableused. In the drawings, and particularly FIGURE 18, the recesses inthebearing plate '70 and 72 are shown to be semi-circular grooves 74,76, 78 and 80.

Bearing plates 743 and '72 are urged together by resilient spacermembers 82 and 84. Side plates 36 and 88 maintain the top and bottomportions 9% and 92 respectively in spaced relation with one another.Resilient members 82 and 84 may be of rubber, or other elastomericcomposition. In general, the other portions of the block can beconstructed of plastic or similar materials as previously indicated. Inthe modification shown in FIGURES 16, 17 and 18, the cables C are woundupon a drum 100. The drum 106 may be rotated by means of a pulley 102driven by a motor pulley 104 from the motor M. It is obvious that anyother type of drive mechanism could be used to wind up the cables C. Aspool or drum not shown could be used to contain the cables prior totheir being fed through the block B onto the drum prior to operating theswitching system.

FIGURES 19 and 20 FIGURES 19 and 20 show another modification in whichthe switching system comprises a series of blocks B1, B2 and B3. Theblocks B1, B2 and B3 are separable one from another. There may be manymore blocks interchangeably associated for various circuit combinationsand the blocks may be held in relationship one to the other by means ofpins 106 and 108 as best shown in FIGURE 20. Another type of contactconnector C is shown in FIGURES 20 and 21 having a series of arms III112, 11.4, 116. Circuit members Y are shown operating on opposedsurfaces of the upright portions of the cross of cable C. Various otherpositions for the members Y can be arranged as desired in the blocks Bwith respect to the various cable designs whether having conductivesurfaces or raised or depressed areas as in the case wheremicro-switches are used. The particular arrangement shown in FIGURES 19and 20 is capable of indefinite rearrangement depending upon the jobrequired.

FIGURES 21 and 22 FIGURES 21 and 22 further illustrate anothermodification in which the members Y are capable of movement in the blockB on an axis transverse to the axis of the cable C. Although thearrangements in FIGURES 21 and 22 are for a rotary motion due to theconfiguration of the cable C; nevertheless, a rectangular block maypermit straight line reciprocable motion of the members Y as in the casewhere the cable is of rectangular or similar configuration. In thedrawings as illustrated in FIGURES 21 and 22, slots 126.), 122 and 124are provided. Members Y are maintained in the slots for rotary action asillustrated by means of bearing grooves 126 and 128. Ribs not shown onthe members Y would ride in the grooves 126 and 122' which would serveas bearing surfaces. For the purposes of illustration, a conductive area130 on one side of the cable is provided as well as a conductive area132 on the other side thereof. The contact 134 is illustrated in contactwith the contact area 130. By moving the bar 136 in a vertical fashion,contact is broken between the contacts 134 and 138. In the case ofcontact 140, vertical motion would make the contact with contact surface132 when a vertical movement upwardly is made of the member Y by movingthe bar 142. It will be obvious, that various arrangements can be madeand that the bar 136 can be dispensed with or can be used to connect anynumber of members Y for movement simultaneously. The slots can be spacedany distance from one another depending upon choice and job to be done.A rib on bead 14-4 is used to maintain the cable C in position withrespect to the block B in order to prevent rotary shifting of theconductive, raised or depressed surfaces with respect to the contacts.

FIGURES 23 to 25 FIGURE 23 shows a cable C having a conductive surfacedepressed for the purpose of avoiding arcing. With the cable moving inthe direction right as illustrated on the drawings, the contact willtravel over the surface 152 until it reaches the edge portion 153. Ifthe contact surface is champfered on the right hand side thereof, in avertical plane, it will suddenly drop downwardly onto the conductivesurface 150 with a snap action due to the spring pressure on the loadedcontact member. Various other devices can be used to reduce arcing whichtends to wear out the contact surfaces.

FIGURES 24 and 25 illustrate a pressure type contact switch which couldbe used to operate in a recess X. Embedded in sleeve which may be ofplastic are conductors 162 and 164. The ends 166 and 168 of the.

wire 170 are embedded or soldered to the conductors 162 and 164. Theconductor 162 has a spring finger 172 which flexes upwardly to an arm174 on the conductor 164. Contact between 172 and 174 closes the circuitof the conductor cable 170. Spurs 176 and 178 lock the sleeve inposition in any one of the openings X of the blocks B. The conductorfinger 172 projects downwardly into the passageway P for the cable C andthe contact is made when the high spots in the cable C of the typeillustrated in FIGURES l1 and 12 move finger 172 into contact with arm174.

FIGURES 26 and 27 FIGURES 26 and 27 illustrate a further modification inwhich a sliding member Y may be moved axially with respect to the cableC. A slot 180 in the block B is provided to allow the member Y to bereciprocated therein. Bearing grooves 182 and 184 maintain the member Yin upright position and serve to guide the member in the slot 180 and tolock it in position during operation. A mere shifting right or left asillustrated in FIGURES 26 and 27 by the arrows is sufiicient to changethe time period during which a particular circuit is programmed. FIGURE26 also illustrates the combination of principles as set out in FIGURE21 in which the slot 180 is accompanied by slots 190 and 192 at rightangles thereto. Other members Y are mounted in a manner similar toFIGURES 21 and 22 for movement in slots .190 and 192 transversely to theaxis of the cable C.

Manual means may be used for moving the members Y or solenoid operatorsor motor mechanisms of any other similar type arrangements may be used.FIGURES 26 and 27 show the cable C having a conductive surface 194connecting the circuit between Y8 and Y10. Y12 is shown out ofengagement with the conductive surface 194. Y12 can be moved into thecircuit of Y8 and Y10, or Y may be moved out of the circuit with Y8, orthe combination of Y8 and Y12 as desired. A shift axially of Y8 willchange the programming period with respect to Y10 or Y12 as desired.

FIGURES 28 t0 3] FIGURES 28 and 29 illustrate another modification inwhich the cables C are in effect endless belts. Pulleys 200, 202, 204and 206 may be actuated through some motor mechanism. In this system,the programming is a repeating type. It is obvious that any number ofendless belts C may be arranged in any fashion and the illustration inFIGURES 28 and 29 is merely one type of combination.

. FIGURE 30 illustrates another type of contact connector showing aprinted circuit 210 passing about surface 212, 214, 216, 218, and 220 tomake a circuit between contacts 222 and 224 while by-passing contact226. FIGURE 31 illustrates a contact connector base 230 ofnon-conductive material having a conductive coating 232 and anon-conductive overlay 234. This arrangement can be used with any cableor connector C where it is necessary to block out a portion of theprinted circuit.

General observation It will be obvious from the above that the speed ofthe cable will determine the length of time a circuit will remain inoperation. It is also obvious that the length of the conductive surface,or the varied portion will determine the length of time a circuit willremain in operation. Similarly a circuit will be inoperative dependingon the length of the non-conductive portion of the cable or the recessedarea as well as the speed this portion has as it moves through theblock. Variations and combinations can be determined for whateverprogrammed circuitry is desired and the circuits printed in advance.Knowledge of the position of the contacts with respect to a known cablewill also permit substitution of new circuits while using old cables andvice versa.
